It is too addictive worth binge watch! What's Good- Yes, concept and plot of this survival drama is not a new thing, but the way it conveys with conviction has no match.
It is high intense drama of human emotions like fear, greed, worrying, anxiety and humanity. Like in 'parasite', it again shows social inequality issues of South Korea.
The series is a high-quality work and It's visuals are strong to build suspense very effectively.
Recommending to watch original Korean audio with English subtitles. And yes, it can be addictive one to binge watch!
